The Liberty Bell Museum (also the Liberty Bell Shrine Museum) is a non-profit organization and museum located in Zion's United Church of Christ (formerly Zion's Reformed Church) in Allentown, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania. The museum is based in the church in which the Liberty Bell, an iconic and globally-recognized symbol of America's independence, was hidden from the British Army by Allentown-area American patriots during the American Revolutionary War from September 1777 to June 1778. The museum was constructed and opened in 1962 and contains exhibits relating to the Liberty Bell and subjects including liberty, freedom, patriotism and local history. It also contains a full-size replica of the Liberty Bell, one of 55 replicas cast in France in 1950 for a U.S. Treasury savings bond promotion, which visitors are permitted to ring. Also on display is Allentown's Liberty Bell, which was cast in 1769 for Zion's Reformed Church and is believed to have been rung on July 8, 1776 to announce the public reading in Allentown of the Declaration of Independence. Zion's Church, built in 1886 to replace the former church on the site, is one of 14 structures in Allentown listed on the National Park Service's National Register of Historic Places; however, the federal law that created the registry provides no protection against actions taken by property owners. The shrine was founded in 1962 by Ralph H. Griesemer and Morgan D. Person.
